A bicycle sprocket assembly comprises a first sprocket, a second sprocket, a first intervening member, and a second intervening member. The first sprocket includes a first sprocket body and a first chain-engagement structure. The second sprocket includes a second sprocket body and a second chain-engagement structure. The first intervening member is positioned between the first sprocket and the second sprocket in an axial direction parallel to a rotational center axis. The second intervening member is positioned between the first sprocket and the second sprocket in the axial direction. The second intervening member is provided radially outwardly from the first intervening member with respect to the rotational center axis. The second intervening member is attached to at least one of the first sprocket and the second sprocket and has an elongated shape extending along a first reference plane perpendicular to the rotational center axis.
